Madonna hosted her annual private Oscars after party at manager Guy Oseary's mansion and the A-List event was tight on security with a number of staff helping guests check-in.

A source told ''There was tons of security and tons of staff checking people in.''

She wasn't the only Hollywood star to don diamonds.

Oscar presenter Anne Hathaway opted for a black Gucci gown, and wore 100-carats of diamond, estimated $1 million, and platinum bracelets.

While 'American Hustle' actress Jennifer Lawrence - who was nominated for Best Supporting Actress but beaten by '12 Years A Slave' star Lupita Nyong'o - donned a beautiful crystal diamond and platinum necklace, worth approximately $2 million.
